I'd really appreciate help- this is due in around 8 hours :"D

atomic #= 1protons equals one Number of neutrons equals to 0 number of electrons equal to 1 mass number equals to 1

2.

atomic number equals to 1 Protons equals to 1 number of neutrons equals to 0 number of electrons equals to 0 because the plus sign means that it loses an electronmass number equals to 1

3.

atomic number 17 number of protons 17 number of neutrons 18number for electrons 18 Because negative sign means It's an anion which means it gains an electron mass number 35

4.

12121210 loses 2 its a cation24

5.

4747108-47 = 6146 loses 1108

6.

161632-16 =1618 it gains 2 electrons32

there u go

Rethink and reinvent
